Ciara and Future welcome 'baby Future'

Ciara is a mom and her fiance, Future, is once again a dad after the R&B singer gave birth to a baby son early Monday morning.

It's a first child for the singer, who posted the vitals Tuesday on Instagram along with a picture showing the boy's little hand.

His name? Future Zahir Wilburn. Despite that tiny hand, he's a big guy, weighing in at 9 pounds, 10 ounces, according to Mom, who confirmed the reported Monday birthdate.

"Baby FUTURE," read a Tuesday morning tweet from the elder Future, the rapper and music producer whose birth name is Nayvadius D. Wilburn. This is reportedly his fourth child.

Ciara was light on her toes right up till mere days before the birth: On Friday she posted a cute video of herself dancing, captioning it, "Ever Seen A Pregnant Lady Crip Walk?:) #BlimpeWalk Goofing Off Before I Hit The Track 2 Walk:) #LoveMusic.#LoveDance. Happy Friday Everyone!!:) XO."

At the end of the video she grabbed her baby bump with a laugh and declared, "I can't even bend down" because her belly "gets in the way."

She announced her pregnancy in January on "The View" when she took her bigger belly public.

Ciara and Future got engaged last October when he gave her a 15-carat ring. She told "The View" that the wedding will happen this year.
